Comprehensive tuning of the Nissan Murano Z51 body: selection and installation of body kit

Crossover owners Nissan Murano second generation (Z51 body) are often faced with the desire to make their car stand out from the crowd, making it more aggressive and sporty. The standard design, although it has its own charisma, over time can seem too calm for dynamic driving. This is where a wide range of aerodynamic body kits come into the picture, capable of radically changing the visual perception of the car, adding power and style.

Installing a body kit is not just about screwing plastic covers to the bumpers. This is a complex process that requires an understanding of body geometry, fastening features and materials. Incorrect selection or installation can damage the paintwork, disrupt aerodynamics, and even reduce safety when driving at high speeds. High-quality tuning must fit harmoniously into the lines Nissan Murano Z51, emphasizing its massiveness, and not overloading the image.

In this article we will look at all types of available solutions, from budget overlays to full-fledged fiberglass kits. You will find out what is different polyurethane from fiberglass, how to properly prepare the body for installation and what nuances need to be taken into account when painting new parts. We will also touch on the legal aspects of making changes to the design of the car so that you can enjoy the result without problems with the traffic police.

Main types of materials for body tuning

The first and most important step when choosing a body kit is determining the material from which it is made. Not only the appearance, but also the durability, price and complexity of installation depend on this. There are several main types of materials on the market, each with its own unique characteristics and applications.

The most popular material for factory and high-quality aftermarket kits is polyurethane. This material has excellent elasticity, which allows it to withstand minor impacts and deformations, returning to its original state. Polyurethane elements such as sills or spoilers are less prone to cracking during installation compared to brittle plastic. However, their cost is higher, and painting requires the use of special primers for elastic surfaces.

Fiberglass (plastic) is a classic choice for aggressive tuning, offering ideal surface smoothness and the ability to create complex shapes. It is lighter than polyurethane, but much more fragile. Any installation error or strong impact may result in cracks or chips that require professional repair. Fiberglass body kits often used in racing series, but for everyday use on Russian roads they require special care.

There are also budget options made from ABS plastic, which is hard and brittle. Such kits are often found in the mass market. They require a perfect fit to the body, as they have no margin for deformation. If the body geometry Nissan Murano Z51 has even minor deviations, hard plastic may not fit into place, which will require modification or the use of additional pads.

Types of aerodynamic kits for Murano Z51

The tuning market offers many options for modernizing the appearance of a crossover, ranging from spot changes to a complete transformation of the image. The choice of a specific kit depends on your aesthetic preferences and budget. It is important to understand that each element affects the overall silhouette of the car.

The most common solution is to install bumper covers. These can be simple black inserts that imitate air intakes, or full-fledged front and rear skirts that visually press the car to the ground. The front skirt is often integrated with splitter, which improves downforce and protects the lower part of the bumper from damage when parking.

• 🚗 Front splitter - creates an aggressive “mouth” and improves aerodynamics.
• 🚗 Side sills - visually lengthen the body and protect the doors from dirt.
• 🚗 Rear diffuser - adds a sporty accent and imitates racing solutions.
• 🚗 Arch covers - protect the body from stones and expand the visual track.

“Widebody” or “Bodykit” style kits deserve special attention, which involve replacing standard bumpers with wider and more voluminous ones. Such decisions radically change the character Nissan Murano, making it look like an SUV or sports crossover. These kits often include fender flares, which allow for larger wheels and more aggressive rims.

Don't forget about the roof. Installation spoiler or a “whale tail” on the roof of the Z51 is a popular way to add dynamics. Spoilers can be either small, integrated into the roof line, or large, protruding beyond the dimensions. They not only improve appearance, but can also affect the car's behavior when driving on the highway, reducing lift.

Body preparation and installation tools

Before you begin installing the body kit, you must carefully prepare the car and work area. The quality of installation directly depends on how well you cleaned and degreased the surfaces, as well as on having the right tools. Skipping the preparation step may result in parts peeling off or corroding under the covers.

You will need a set of high-quality tools: a screwdriver with a set of bits, a set of screwdrivers, 8, 10 and 12 mm wrenches, as well as a clip extractor for removing standard plastic elements. Don't forget about masking tape and a marker to mark the holes. If you plan to paint the parts yourself or before installation, you will need a sander, sandpaper and degreaser.

Pay special attention to the condition of the standard fasteners. Often when removing old bumpers, the plastic clips break. Stock up on new clips and self-tapping screws, since reusing old elements is unreliable. If you are installing elements with double-sided tape, make sure the surface is perfectly flat and dry.

⚠️ Attention: Do not use aggressive solvents such as acetone or gasoline to degrease painted body surfaces. This may damage the paintwork and cause blistering of the paint underneath installed components. Use specialized antistatic agents or isopropyl alcohol.

If you decide to drill additional holes for fixing, do so as accurately as possible. Use drills with a depth stop to avoid damaging interior trim or electrical wiring. After drilling, be sure to treat the edges of the holes with an anti-corrosion compound to prevent the metal from rusting.

Comparison of characteristics of popular kits

To choose the perfect body kit, you need to compare the characteristics of different offers. The table below provides comparative data on the most popular types of kits for Nissan Murano Z51which can be found on the market. This will help you make an informed decision based on facts.

Kit type	Material	Difficulty of installation	Durability	Cost
Bumper covers	ABS plastic	Low	Average	Low
Full Bodykit	Fiberglass	High	High (if careful)	High
Sports body kit	Polyurethane	Average	Very high	Medium/High
Local elements	Composite	Low	Average	Low

Please note that cost is not always an indicator of quality. Cheap kits made from cheap plastic can quickly crack or fade in the sun. At the same time, expensive fiberglass kits require professional fitting, otherwise the gaps will be uneven, which will spoil the appearance.

When choosing, also consider compatibility with your standard elements. Some kits are complete bumper replacements, while others are bumper kits that snap on top of the stock parts. It is important to make sure that the new elements do not interfere with parking sensors or rear view cameras, if yours has them. Nissan Murano.

Features of painting and finishing

If you purchased a body kit in black and plan to paint it in body color, the process requires careful preparation. Most new parts have a factory primer that is not intended for direct painting and requires sanding. The quality of the paint determines how organically the new body kit will look on the car.

First you need to remove the parts from the car (if possible) or securely seal the adjacent elements. Sand the surface with P400-P600 grit sandpaper to create adhesion. Then apply a layer acrylic primer, which will fill micropores and level the surface. After the primer has dried, sand again with P800-P1000.

• 🎨 Use base paint exactly matched to the color code of your car.
• 🎨 Apply varnish in 2-3 layers to add depth and shine.
• 🎨 Allow the paint to dry completely before installing (minimum 24 hours).

Regular varnish on hard plastic will crack over time due to vibrations and temperature changes. This is a critical point that is often overlooked when painting yourself.

⚠️ Attention: Never install freshly painted parts on a car immediately after the varnish has dried. Residual chemical reactions may last for several days and the coating may deteriorate if exposed to dust or moisture.

If you are not confident in your abilities, it is better to entrust painting to professionals in a specialized service. They use chamber equipment that ensures there is no dust and the layers are applied evenly. This is especially true for Nissan Murano Z51, where complex body shapes require expert painter work.

Legal aspects and security

In Russia, legislation strictly regulates changes to the design of vehicles. Installation of a body kit, if not provided by the manufacturer, is considered a design change. This imposes certain obligations on the car owner.

If you are installing elements that do not affect safety and do not radically change the appearance (for example, small overlays), this often goes through without registration. However, installing a full wide-body body kit or changing the clearance requires going through the legalization procedure. Ignoring this rule may result in fines and a ban on operation.

What to do if the traffic police requires you to return the factory appearance?

If the inspector identifies a design non-compliance, you will be issued a notice. You need to either dismantle the elements or go through the procedure of legalizing the changes at the State Traffic Safety Inspectorate by providing certificates for the parts and an expert opinion.

It is also important to consider safety. A larger front splitter can lower the ride height, causing bumper damage over bumps. Flared arches can create additional obstacles when turning the steering wheel or driving off-road. Aerodynamics must be balanced so as not to impair the vehicle's stability at high speeds.

Make sure that installed elements do not obscure lights or license plates. Violation of lighting rules is a gross violation of traffic rules and entails deprivation of rights or a large fine. Always check the functionality of the headlights and brake lights after installing any body parts.

Frequently asked questions from Nissan Murano Z51 owners

Crossover owners often ask questions about the compatibility and durability of tuning. Below we have collected answers to the most common ones to help you avoid common mistakes when upgrading your car.

Is it possible to install a body kit without painting?

Yes, you can. Many kits are sold in matte or gloss black, which creates a stylish contrast with the body. However, make sure that the color of the plastic does not fade in the sun, otherwise the contrast will disappear after a year.

How to attach a body kit with double-sided tape?

Use a quality foam backed tape (such as 3M VHB). Clean the surfaces with alcohol, heat the tape with a hairdryer before applying the sticker and press the part firmly for 30 seconds. Do not wash the car for the first 48 hours after installation.

Does body kit affect fuel consumption?

Yes, aggressive body kits increase aerodynamic drag, which can slightly increase fuel consumption, especially at speeds above 100 km/h. However, the difference is usually small and amounts to 0.3-0.5 liters.

What to do if a part is cracked?

For fiberglass, use epoxy resin and fiberglass cloth. For polyurethane, it is better to contact a body shop, since welding plastic requires special equipment and skills.

Do I need to remove the bumper to install the threshold?

In most cases, yes. Fastening elements are often located behind the bumper, and access to them is possible only after dismantling it. This also allows you to check the condition of hidden areas of the body for corrosion.
